He's recently split from his girlfriend Taylor Swift but the failed romance seemed a million miles from Harry Styles' mind as he enjoyed a raucous 19th birthday party on Friday night.
The One Direction star let his hair down as he partied with his showbiz pals and was even treated to a lap dance from an underwear clad girl at the after party.
The singer had first headed out to a club in trendy east London, before eventually going back to a pal's nearby house.

Don't mind me! Harry was seen chatting to his pals as the girl continued her dance as he partied until the early hours of the morning

And it seems his friends were intent on him having a good time as pictures show one girl stripping to her underwear and doing a dance for the teenager.
Styles can be seen grinning from ear to ear in the pictures as the girl, who is thought to be a belly dancer, treated him to the moves.
And in other images, which were posted by a fan at the party on Twitter and on fan sites, Harry is seen posing with party guests as he continued the wild night.
He's managed to forge a close friendship with a number of stars in a short space of time since becoming an international pop star.

So Harry Styles, of course, decided to celebrate his 19th birthday with his new best friends Nick Grimshaw and Pixie Geldof on Friday night before mingling with the girls at his bash.
Although what might come as a surprise to his One Direction fans is his bandmate Liam Payne was out partying on the same evening... but over the other side of London.
Styles opted to head out in trendy east London, hitting up night spot The Alibi for the first part of his night.
